Here's an article in the NYT about the DVD for "Capturing the Friedmans":

We heard from theater managers that there was a problem," [the director] Jarecki said. "People weren't leaving after the film. They were sitting in their seats, arguing about things, so they couldn't clean the theater."

Mr. Jarecki and his fellow filmmakers began interviewing those who lingered. "People had strong reactions, they wanted to know more, talk more, and we realized this could be a starting point for the DVD," he said. One segment on the second disc answers frequently asked questions about the case and the members of the Friedman family. What are their relationships today? Why did they record their lives and troubles in such detail on videotape, an extraordinary part of the movie?

This film should be added to those lists of movies about law.

The person I saw this movie with and I left the theater, both sure we knew the truth about the events represented in the film. But we had opposite positions. I've ordered the DVD--so I'm going to need to plunge back into the argument.
